如何显示相同列但具有不同值的结果

Question

Here I'm returning data from my database which have a title_heading column and it has a title column.

 id     title_heading    title
 
 1     HTML Tutorial     Home
 2     HTML Tutorial     Overview
 3     HTML References   Tags

but now I wanted to show the results like this in my view:

**HTML Tutorial**

**HTML References**

Answer 1

i have two idea on this.. first normalize that table into two table..

heading : [id,name] subTitle : [id, name, heading_id]

then you make oneToMany Relationship in laravel

second you can use nested loop it and push it into array..
